Abstract Large-scale bicycle network design, safety, and crash estimates largely depend on network-wide bicycling volume estimation. Previous studies developed direct demand models on a smaller scale (e.g. city or county) where bicycle count and ...Practical Applications Agencies often need to estimate bicycle volumes at the link level across entire networks for planning, safety, and design purposes. This study uses expansion factors to introduce a method for converting short-term site volume data.

Cities around the world are turning to non-motorized transport alternatives to help solve congestion and pollution issues. This paradigm shift demands on new infrastructure that serves and boosts local cycling rates. This creates the need for novel data sources, tools, and methods that allow us to identify and prioritize locations where to intervene via properly planned cycling infrastructure. Here, we define potential demand as the total trips of the population that could be supported by bicycle paths. To that end, we use information from a phone-based travel demand and the trip distance...

Airports and Bicycles: What are the Obstacles and Incentives for Operators 1 to Improve Bicycle Access?

Orrick, Phyllis

2013

In this paper we use a case study approach to examine how airport operators are addressing bicycle access to their properties and the motivations and obstacles they face, in light of new policies to integrate bicycles, along with transit and walking, into transportation planning, design and construction, and to increase bicycles’ role in the transportation system. Eight influential elements emerged from our review of policy documents and research literature. We used them to guide interviews with key informants. The eight elements are: governance structure, location, access roads, self-...

Optimal Design of Transit Networks Fed by Shared Bikes

Transit systems are designed in which access and egress can occur via a shared-bike service. Patrons may walk to shared-bike docking stations nearest their origins, and then cycle to their nearest transit stations where they deposit the bikes. The travel pattern is reversed when patrons cycle from their final transit stations on to their destinations. Patrons choose between this option and that of solely walking to or from transit stations. Shared bikes are priced to achieve the system-optimal assignment of the two feeder options. Transit trunk-line networks are laid-out in hybrid fashion...

To Pool or Not to Pool? Understanding Opportunities, Challenges, and Equity Considerations to Expanding the Market for Pooling

On-demand mobility services such as bikesharing, scooter sharing, and transportation network companies (TNCs, also known as ridesourcing and ridehailing) are changing the way that people travel by providing dynamic, on-demand mobility that can supplement public transit and personal-vehicle use. Adoption of on-demand mobility has soared across the United States and abroad, driven by the flexibility and affordability that these services offer, particularly in urban areas where population density and land use patterns facilitate a reliable balance of supply and demand. The growth of app-based...

Improving Bay Area Rapid Transit (BART) District Connectivity and Access with the Segway Human Transporter and Other Low Speed Mobility Devices

Access to transit stations is a significant barrier to transit use in many urban regions. Parking during peak hours is often limited, and many individuals are only willing to walk about a quarter mile to transit stations (Cervero, 2001). While there are some effective feeder services (e.g., shuttles) that help extend the range of transit access, these systems are limited because of fixed routes and schedules. A number of strategies have recently been implemented to improve transit access and transit use, including bicycles, electric bicycles, carsharing, and personal neighborhood electric...

The North Carolina Physical Activity Policy Research Center: Making Connections with North Carolina Planners

Physical activity participation for youth and adults is suboptimal in North Carolina. There is growing interest among policy makers to promote physical activity, yet research in this area is limited. The North Carolina Physical Activity Policy Research Center was established in 2004 to conduct research on physical activity and policy. This cross-disciplinary center brings together faculty and researchers from the University of North Carolina School of Public Health and the College of Arts and Sciences. Current projects include understanding and documenting polices that affect walking...

STC Matching Grant Annual Report

Daniel Rodriguez
2008

While the conventional approach to safety planning has emphasized crash analysis with police-reported crash information, transportation professionals increasingly recognize the importance of identifying potential crash risk and considering environmental characteristics. In this proactive approach, individuals’ perception of crash risk provides important information in identifying potential crash risk. As built environment characteristics such as the presence of crosswalks, sidewalks, and number of lanes, are expected to influence the levels of pedestrian and bicycle safety, this study...

Hot, Congested, Crowded and Diverse: Emerging Research Agendas in Planning

This special issue explores emerging research agendas in planning. It brings together scholars from diverse schools working on new areas of research and application in urban design and planning. Emergent research agendas include both novel areas of research and important shifts in the direction of a research area. The challenge for planning schools is to reflect critically on these changes and develop long-term research agendas that can better position our field in society and academia, and provide a basis from which to assess our academic programmes. The chapters presented in this issue...
